The weather in Dallas-Fort Worth can be unpredictable when it comes to freezing temperatures and snow. Even though we don’t deal with winter weather very often, dropping mercury and winter storms mean frozen pipes are a more common problem for Texans to face.
Texas winters have been getting progressively colder, which means you’re more likely to see your pipes freezing. Because many Texans have no experience dealing with frozen pipes, we’ve put together this step-by-step guide on how to unfreeze pipes. Thawing a frozen pipe is quick and easy, but you’ll want to identify and resolve the issue the right way. Frozen pipes risk rupture and expensive damage. Here are our recommendations:
1. How to Find a Frozen Pipe
Once temperatures drop, check your plumbing regularly. Finding frozen pipes before they burst is crucial. The pipes most likely to freeze in your home are:
- Exposed under sinks
- Around your water meter
- In crawl spaces
- Near exterior walls
- Outside
To check these pipes, look for any obvious signs of freezing such as being cold to the touch or having a coat of frost. Next, test whether their attached fixtures work. If you find one that doesn’t work, it means you’re close to the frozen section. Follow that faucet back to an exposed or uninsulated section of pipe and you’ll likely find the frozen section.
2. Turn On the Faucet the Pipe Feeds into
Determine which faucet the frozen pipe supplies water into and open it up. Turn both the hot and cold knobs. This serves two purposes:
- It relieves pressure inside the pipe, which can help prevent damage.
- When the pipe thaws, the melted water has an outlet.
Once you follow the steps below and see water dripping out of your faucet, you’ll know you successfully thawed out your frozen pipe. Give it time for all ice to loosen and melt.
3. How to Thaw Frozen Water Pipes
There are several ways to thaw a frozen pipe. The important thing is to begin with the section closest to the faucet so that the melted water has an escape route. Melting the water that is trapped in the middle of a frozen pipe could cause it to burst. Also, never use an open flame on your home plumbing. Try one of these methods to unfreeze your iced pipes:
- Warm towels. Soak towels in hot water and wrap them around the affected pipes. With a bucket underneath, you can pour hot water over the wrapped towels to expedite the process.
- Hair dryer. Aim your hair dryer – on low heat- at the target area and keep the heat moving to avoid overheating one section or another. Be careful to avoid shock by not getting your hair dryer wet. Similarly you can use a heat gun for frozen pipes.
- Heat lamp. A heat lamp can direct steady, gentle heat to the frozen pipe. As with the hair dryer, be sure to avoid getting your lamp wet.
- Heating tape. Your local hardware store should carry heating tape or electric wraps designed to warm cold or frozen pipes (unless everyone else is buying them at the same time). Keep some stocked for emergencies.
- Space heater. For small areas, like under a cabinet or in a crawl space, use a space heater to thaw pipes. They work well to warm the surrounding air.
You’ll know you’re thawing the ice inside the pipe when water starts running out of their respective faucets. If the frozen pipe is hidden inside your walls, underground or out of reach, we recommend calling plumbing professionals.
4. Prevent frozen pipes in the future.
Once you’ve thawed your pipe, you’ll want to keep it from freezing again. To do that:
- Turn your home’s heating on as soon as temperatures drop.
- Keep interior doors open to help warm air flow throughout your home.
- Run your water fixtures regularly, especially in parts of the home where the pipes are exposed to cold.
- Open hot water faucets ever-so-slightly if it’s going to be especially cold – the warm running water will keep pipes warm.
- Insulate at-risk sections of pipe. This is relatively easy and inexpensive with pipe insulation from your local hardware store.

Frozen Pipe FAQ
Will frozen pipes thaw on their own?
Eventually, yes. In Texas it’s likely that pipes will thaw sooner than later but extended winter storms can make frozen pipes a definite danger. If your pipes become frosty overnight but the forecast is warm, you’re probably fine. If you see long-term cold ahead, don’t risk your pipes bursting, address the problem immediately.
How to thaw frozen pipes in the wall?
If the pipes in question are inside a wall, you have a few options:
· Turn up the thermostat so that your entire home warms.
· Aim a heat lamp at the wall section in question.
· Cut an access panel in the wall and use the above methods to thaw the pipe.
· Call a professional.
If pipes are frozen, should I leave the faucet on?
Yes. Until the pipe has fully thawed, leave your faucet open for the water to escape. Leaving faucets open at a trickle during cold weather can prevent them from freezing up.
Will running hot water unfreeze pipes?
It’s unlikely that simply turning on hot water will be enough to thaw a pipe unless the frozen area is relatively small. Running a hot water trickle can be a good preventative to keep pipes from freezing in the first place.
Why do pipes burst?
As water freezes, its molecular structure changes to a hexagonal shape. This shape takes up more space than the molecules in liquid form but the change alone is not the reason pipes burst. What happens is that built up ice pushes up against the liquid water and blocks it from flowing. The water behind the ice can always push back to its source but water in front of the ice has nowhere to go – especially if your faucet isn’t open. Eventually the pressure will burst your pipe in an area that wasn’t actually frozen.
What should I do when a pipe bursts?
Turn off your water supply immediately at the main shut off valve. Prevent damage to your home by stopping all water from coming into your home. Your main shutoff valve should be near your water meter where the city water line connects to your home. Some experts recommend shutting the main valve before thawing pipes to prevent potential disaster if a pipe bursts during the melting process.
How to thaw frozen pipes underground?
If your toilet won’t flush or your drains are backed up because of a frozen sewer line underground, your best bet is to call a professional. We can use a boring tool with a warm water jet to open frozen pipes that are otherwise difficult to reach.
How to fix a burst frozen pipe?
Have a professional plumber perform the work. Not only can they replace the damaged pipe, but they can also make sure no other parts of your plumbing system were compromised by the break. And they will do it all to local code.
